HOHSESHOE.

SPECIFICATION forming part of Letters Patent No. 787,446, dated April18, 1905.

Application filed November 28, 1903. Serial No. 183,077.

To all whmn it may concern.-

of the United States of America, and a resident of Vashington, Districtof Columbia, have invented certain new and useful Improvements inHorseshoes, of which the following is a specification, reference beinghad to the accompanying drawings, in which- Figure 1 is a perspectiveview of a shoe provided with my improved calks; Fig. 2, a similar viewinverted with the calks removed. Fig. 3 is a detail perspective of oneof the heel-calks removed. Fig. 4 is a similar view of the toe-calk.Fig. 5 is a similar view of another form of toe-calks, and Figs. 6 and 7detail sections through the heel and toe calks.

The object of this invention is to provide a construction that willpermit the calks to be changed without the intervention of skilled laborand without removing the shoe from the animals foot, as more fullyhereinafter set forth.

The shoe proper is constructed in the usual manner except that at eachheel and at the toe portion it is provided with a substantiallyrectangular integral projection a on its wearing-face. The projection oneach heel part is substantially the width of the shoe and is providedwith a hole through it, the hole extending from the front to the-rearface of the projection and tapering slightly forwardly.

Each heel-call: consists of a wearing:block b, which is flat on itsupper surface to adapt it to fit squarely against the enlargement a, andis provided at its rear upper edge with an upward-extending part c,which bears flat against the rear end of the shoe. Formed integral withthis upper projecting part c and projecting forwardly from it is atapering pin (Z, which nicely fits the hole in the projecting part a andis long enough to extend beyond the forward face thereof. This pin (Z isprovided with a transverse hole 0, through which a split pin or a nailor a piece of wire may be passed to lock the calk to the shoe, thislockpin bearing directly against the forward face of the projection a.These calks may be sharpened, as shown in Fig. 3, or made blunt on theirwearing-faces, as shown in Fig. 6. The toe-calk is constructed insubstantially the same manner, it consisting of 1 Be ltknown that I,FRITZ HERZOG, a citizen a wearlng portion f, an upward-extending part gat the forward edge of the wearing part midway between its ends, and anintegral rearwardly-projecting pin It, adapted to'fit a tapering holeformed in the projection a at the toe of the shoe. The projection a isre cessed at its forward end to receive the part g, this recess dividingthe part a into two bearing parts a, one at each side of the projectiong. This toe-calk may be sharpened,

as shown in Fig. 4, or made blunt, as shown in Fig. 5. The pin it isprovided with a transverse hole 2', through which a suitable locking-pinis passed to removably lock the toecalk in place.

With the foregoing construction it Will be obvious that the calks may bereadily changed from one kind to the other by simply removing thelock-pins, and it is obvious that this may be done without removing theshoe from the horse or employing skilled labor. This shoe is notintended for use without calks. It will at all times be used with eitherone form of calk or the other, according to the weather conditions.

An important feature lies in providing at each heel and at the toeportion an integral projection on the shoe adapted to receive the pinsand take up the shock and strain, relieving the shoe proper of suchshock and strains and providing a broad solid bearing for the calks.

Another feature lies in forming the pins (Z and lb integral withupward-projecting lugs on the calks, thus avoiding the use of bolts andthe weakening of the upward-projecting lugs.

Still another feature of importance lies in extending theupward-extending parts 0 and 9 far enough to bear against the body ofthe shoe, so as to thereby not only brace the calks, but relieve theprojections a from part of the strain and shocks.

It will be observed that each of the calksupporting projections consistsof a single solid part having a continuous flat bearingsurface ofsubstantially the width of the shoe, thereby not only affording asubstantial support for the calk, but also providing a support for thelock-pin without weakening the body of the shoe, the holes for thelock-pin being extended entirely through the projections at points belowthe wearing-face of the shoe proper, so that their projecting ends shalllie just back of the calk-supports and close to the wearing-face of theshoe, where they will be out of the way and sufiiciently protected.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A horseshoe provided at each heel part and the toe part with anintegral depending calk-support substantially the Width of the shoe andhaving a flat unbroken bearing-face, each calk-support being providedwith a lockpin hole through it at a'point below the wearing-face of theshoe, a call; bearing upon and covering said flat under surface of eachcalksupport and having an upwardsextending part bearing against one sideof the calk-support, and a lock-pin attached to said upward-extendingpart of each calk and passing through the lock-pin hole in thecalk-support, for the purposes set forth.

2. A horseshoe provided with a removable toe-calk and a dependingintegral calk-support at each heel portion, each of these calksupportsbeing of substantially the same width as the shoe and provided with alock-pin hole through it at a point below the wearing-face of the shoe,a call; bearing upon and covering the under surface of each calk-supportand having an upward-extending part bearing against the rear face of thecalk-support and the end of the shoe proper, and a lock-pin attached tosaid upward-extending part of each calk and passing through saidlock-pin hole and terminating beyond the front wall of the calk-supportjust under the wearing-face ot' the shoe, for the purposes set forth.

In testimony whereof I hereunto afiiX my signature, in the presence oftwo witnesses, this 25th day of November, 1903.
